Implement new accounts API query options

[butonic]

We updated the api to follow the google recommendations and use LDAP as the storage backend.

• we introduce a new ldap attribute ownclouduuid to store a uuid for ocis accounts

part of https://github.com/owncloud/ocis-glauth/issues/13

@refs any Idea how we could provision users?
I guess we need a cli to add them?
This is a marshaled account I wrote by hand:

{
  "key": "1-2-3-4",
  "payload": {
    "account": {
      "issuer": "https://localhost:9200",
      "password": "relativity",
      "standard_claims": {
        "sub": "1234",
        "preferred_username": "einstein",
        "name": "Albert Einstein",
        "given_name": "Albert",
        "family_name": "Einstein"
      }
    }
  }
}

password is not encrypted ... hm need to fix that

I think the import command was meant to do that 🤔

Adding the Blocked label because #22 will be merged first. Once we merge all PR on ocis, ocis-accounts, ocis-settings and ocis-proxy, work on this will resume.

This is strictly for migrating users from another source. The accounts-service should have a seperate command to create users from cli.

rebased on #22, unblocking

will implement query parsing tomorrow

It turns out upstream does not implement LdapAdd or LdapDelete messages, so we will change the architecture to a sync based approach where all users and groups are stored by ocis-accounts directly.

We will revisit this when time permits. For now we are going with a sync based approach in a new PR.
